The simple act of talking face-to-face with another human can trigger hormones that relieve stress when you're feeling agitated or insecure. Even just a brief exchange of kind words or a friendly look from another human being can help calm and soothe your nervous system.

If you don’t have any close relationships, or your relationships are the source of your stress, make it a priority to build stronger and more satisfying connections. Read: Making Good Friends
Concordant with the functional roles of the brain structures that exhibit increased gray matter volumes, regular exercise over a period of several months has been shown to persistently improve numerous executive functions and several forms of memory.       In particular, consistent aerobic exercise has been shown to improve attentional control , [note 3] information processing speed , cognitive flexibility (., task switching ), inhibitory control , [note 4] working memory updating and capacity, [note 5] declarative memory , [note 6] and spatial memory .        In healthy young and middle-aged adults, the effect sizes of improvements in cognitive function are largest for indices of executive functions and small to moderate for aspects of memory and information processing speed.   It may be that in older adults, individuals benefit cognitively by taking part in both aerobic and resistance type exercise of at least moderate intensity.  Individuals who have a sedentary lifestyle tend to have impaired executive functions relative to other more physically active non-exercisers.   A reciprocal relationship between exercise and executive functions has also been noted: improvements in executive control processes, such as attentional control and inhibitory control, increase an individual's tendency to exercise.
